Credit history does not travel with you
This surprises almost every newcomer: the credit history you built in your home country does not transfer to the United States. US bureaus, Equifax, Experian, and TransUnion, only track activity inside the US, so on day one you have no file at all, regardless of how responsible you were abroad.
That is not a judgment on you; it is just how the system is built. The goal is not to fix anything, it is to begin creating a US record from scratch. The encouraging part is that the path is well worn, and many people establish a usable file within a year of steady activity.
A thin or empty file mostly limits you at the very start, when some lenders and landlords cannot see any history to judge. Each account you open and pay on time starts filling that gap quickly.
You may not need a Social Security number to start
A common myth is that you must have a Social Security number to build US credit. In reality, many banks and lenders accept an Individual Taxpayer Identification Number, or ITIN, which the IRS issues to people who need a tax ID but are not eligible for an SSN. If you file US taxes, you may already have one.
With an ITIN, or an SSN if you have one, you can open many starter products. If you do get an SSN later, the credit history you built under your ITIN can generally be linked so you keep your progress. It helps to keep good records of the accounts you open under either number.
Open your first US accounts
A secured credit card is one of the most reliable starting points. You place a refundable deposit that becomes your limit, use the card for small purchases, and pay it off, and the issuer reports to the bureaus like any card. Many secured cards accept an ITIN and have no credit history requirement.
A credit-builder loan is another good foundation, adding installment history while you save, and many community development credit unions offer them to newcomers with an ITIN. If you have family in the US with a well-managed card, being added as an authorized user can also put positive history on your new file.
Credit unions and banks that serve immigrant communities are often the most welcoming first stop, and some report that they specialize in newcomers. Confirm whichever product you pick reports to all three bureaus.
Build the habits US scores reward
US scoring rewards the same behaviors everywhere: pay on time and keep your balances low relative to your limits. Set up autopay so you never miss a due date, since payment history is the biggest factor and a single late mark hits a brand-new file hard.
Keep your spending to a small share of your credit limit and pay it off monthly. You do not need to carry debt or pay interest to build credit, a myth that costs people a lot. Using a card lightly and paying it in full gives you the full benefit at no cost.
Grow and protect your new file
Give your first accounts six months to a year to establish a pattern, then add a second type of credit so your file shows both revolving and installment history. Check your three reports regularly, which is free and never lowers your score, to confirm everything is reporting accurately.
Protect yourself from scams that target newcomers with promises to build credit fast or guarantee approval for a fee. Legitimate credit building is steady and mostly free. If an error ever appears on your report, you have the right under US law to dispute inaccurate information yourself, at no cost.
Starting a US credit file from zero is very doable, and Subefy is built for newcomers, matching you to ITIN-friendly starter options you are likely to qualify for, monitoring all three bureaus, and guiding you toward a mortgage-ready file. Estimates are educational, results vary, and no specific result is guaranteed.
